   It is designed to prevent electromagnetic interference by avoiding co-channel operation with systems that predated Wi-Fi, such as military radar, satellite communication, and weather radar, and also to provide on aggregate a near-uniform loading of the spectrum (uniform spreading). [1] It was standardized in 2003 as part of IEEE 802.11h.

   Wi-Fi positioning system (WPS, WiPS or WFPS) is a geolocation system that uses the characteristics of nearby Wi‑Fi access points to discover where a device is located. [1]It is used where satellite navigation such as GPS is inadequate due to various causes including multipath and signal blockage indoors, or where acquiring a satellite fix would take too long. [2]

   The problem, however, is the coexistence between these heterogeneous wireless networks. To address the coexistence problems in those bands, the IEEE has started the 802.11h Working Group to make recommendations for better future coexistence. It addresses problems like interference with satellites and radar using the same 5 GHz frequency band.
